<p>Impingement cooling of a jet engine subassembly, such as a combustor. Adjacent raised corrugation portions and intervening plate portions (having impingement cooling holes [50]) of a corrugated plate [40] define coolant channels [54,62] in fluid communication with the engine compressor. Dividers [56] positioned transverse to the corrugation portions have a top side attached to a bottom surface of the plate portions and have a bottom side attached to the combustor liner [36]. Corrugation portions define therewithin return channels [62] in fluid communication with post-impingement cooling air. The dividers prevent crossflow between the impingement cooling air and the post-impingement cooling air. <IMAGE></p> |
